U-boot support [https://github.com/NixOS/nixpkgs/pull/32553#issuecomment-373915787 has been added 2018-03-18]. The bootloader with SPL can be downloaded from these location:

First follow the [[NixOS_on_ARM#Installation|generic installation steps]] to get the installer image on an SD card or the eMMC. A compatible eMMC to SD may be required to flash the eMMC. If you do not have one available, it is possible to boot another operating system on the A64-LTS and from there <code>dd</code> to the eMMC.

The Pine A64-LTS is equipe with a 4MB SPI NOR flash chip. The CPU will read the bootloader from it, after trying the SD card and the eMMC.

Flashing u-boot to the SPI NOR flash will allow booting the <code>sd-image-aarch64.img</code> based images without further manipulating the image or the boot device (e.g. without embedding u-boot to the usb drive). It may also allow booting UEFI compliant AArch64 images, though this is unverified.

Once complete, unplug the power from the Pine A64-LTS, unplug the Pine A64-LTS from the host computer, and try booting without storage devices, but either serial or HDMI. When successful, u-boot will start, and eventually try to network boot.

It is possible, through using a u-boot bootloader built from the u-boot-sunxi tree, to write to the SPI NOR flash. The [https://github.com/ayufan-pine64/bootloader-build ayufan-pine64/bootloader-build] has such a build. Using the released <code>.img</code> files, it is possible to write their custom build or erase their custom build. From their custom build, it is possible to write to the SPI NOR flash using the <code>sf</code> command<ref>https://github.com/ayufan-pine64/bootloader-build/blob/d7e891cbee8a559ea50cf25ee18aa9d7b4ea9d58/blobs/flash-spi.cmd#L11-L13</ref>.
